Agent Lightning
AI Development
A Microsoft-built training framework that optimizes AI agents with reinforcement learning, automatic prompt optimization, or supervised fine-tuning — with near-zero code changes to your existing agent, in any framework.
ART
AI Development
Give your LLM agents on-the-job training—ART lets you apply GRPO reinforcement learning to any multi-step agentic workflow with minimal code changes.
headroom
AI Development · Developer Tools
Compress everything your AI agent reads — tool outputs, logs, RAG chunks, and files — before it reaches the LLM, achieving 60–95% fewer tokens with the same answers.
OpenViking
AI Development · AI Memory · Databases
An open-source context database that gives AI agents a unified filesystem for memory, resources, and skills with hierarchical tiered retrieval.
MemPalace
AI Agents · AI Development · AI Memory
Local-first AI memory with verbatim storage, pluggable backends, and 96.6% retrieval recall on LongMemEval — no API key required.
sirchmunk
AI Development · Data Engineering
Drop your files and search them instantly — no vector DB, no indexing pipeline, just raw data queried by a self-evolving intelligence layer.
CertMate
Devops · Security
Automate SSL certificate lifecycle across any CA, 24+ DNS providers, and every major secret store — with a REST API, web dashboard, and built-in MCP server for AI-driven ops.
Flowfile
Data Engineering
Visual ETL that compiles to Polars — build pipelines on a canvas, export as standalone Python, and run anywhere without platform lock-in.
Databasement
Databases · Developer Tools · Devops
Self-hosted database backup manager with a web UI for scheduling, encrypting, and restoring MySQL, PostgreSQL, MongoDB, SQL Server, SQLite, Firebird, and Redis to S3, SFTP, Samba, or local storage.
